SINOLAIR STUART, OF PLAINFIELD, NEV- JERSEY.

CONSTRUCTION OF SHIPS OR OTHER VESSELS..

SPECIFICATION forming part of' Letters Patent. No. 429,290, dated June3, 1890.

Application filed April 5, 1890. Serial No. 346,752. (No model.)

To all whom it may concern.:

Be it known that I, SINCLAIR STUART, of Plainiield, in the county ofUnion and State of New Jersey, have invented a new and usefulImprovement in the Construction of Ships and other Vessels, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to vessels constructed entirely of iron or ofsteel, and to what are known as composite vessels, constructed partly ofiron and partly of steel or partly of iron or steel and partly of Wood.

Its object is to build sue-h vessels of great strength and to providefor the distribution of the strength of the different parts according tothe requirements with a less Weight of material; and to this end `itconsists in the novel constructions of the frames of suoli vessels, ashereinafter described and claimed.

Figure l represents a transverse section of parts of one side and of,the bottom of a vessel, and showing afront view of a frame illustratingmy invention. Figs. 2 and l3 represent, on a larger scale than Fig. l,transverse sections of the frame, taken in the line @o oc of thatfigure, illustrating some differences of construction which are withinthe scope of my invention. Fig. 4 represents a transverse section on thesame scale as Figs. 2 and 3 of the frame in the line y y of Fig. l. Fig.5 represents a transverse section on the same scale as Figs.'2, 3, and 4of the frame, taken in the line z z of Fig. l.

Similar letters of reference designate corresponding parts in all thefigures.

A designatesa channel-iron arranged in the vvessel with its iianges aprojecting in the direction ofthe length of the vessel. Thischannel-iron runs through the bottom, the bilge, and the sides of thevessel, as maybe seen by reference to Fig. l, and constitutes a main andreverse frame at the sides of the vessel, but a main frame only at thebottom.

B is a Hoor-plate running through the bottom of the vessel and up intothe bilge, Where it is represented as terminating at b. This plate isriveted, as shown atv., to the web of the channel-iron frame A. The saidplate may be of any depth that may be considered desirable, generallyincreasing in depth from the bilge toward the central keelson C ofthevessel.

of the Hoor-frames and up to the top of the bilge, and the so-extendedportion is riveted to the channel-iron A. These angle-irons constitutereverse frames in the bilge and bottom of the vessel. In some parts ofthe vessel I propose only to use one of these angle-'iron reverseframes, as shown in Fig. 2. In other parts Where greater strength isrequired, as under engines, the boilers, or thrustbearings for ascrew-propeller, I should use two such frames, as shown in Fig. 3.

By the above-described combination of channel-iron main frame, angleironreverse frame, and floor-plates I am enabled to give the vessel verygreat strength in proportion to the Weight of material employed.

lVhat I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination, in the frame of a ship or other vessel, of achannel-iron which runs through the bottom, the bilge, and the sides ofthe vessel and constitutes a main and a reverse frame at the sides, buta main frame only at the bottom, a iioor-plate which runs through thebottom and up into the bilge and is riveted to said channel-iron, and anangleiron which is riveted both to the upper edge of the floor-plate andto the inner part of the channel-iron to form a reverse frame in. thebilge and bottom of the vessel, substantially as herein described.

2. The combination, in the frame of a ship or other vessel, of achannel-iron which runs through the bottom, the bilge, and the sides ofthe vessel and constitutes both a main and vreverse frame at the sides,but a main frame ioo
